Description
Technical field
The present invention relates to engine cool field, particularly to a kind of thermostat base.
Background technology
Current engine thermostat base is primarily used to place thermostat, the coolant temperature of thermostat sensing thermostat base intracavity, open thermostat in good time, but the existence of some abnormal conditions, as thermostat base intracavity coolant connects the most smooth with engine coolant, or thermostat base intracavity coolant is not enough, thermostat all can be caused to postpone to open or can not be normally-open, the phenomenon boiled easily occurs.
Summary of the invention
It is an object of the invention to provide a kind of thermostat base, it is to avoid the generation of phenomenon of boiling.
For reaching above effect, the technical solution used in the present invention is: a kind of thermostat base, it is provided with thermostat between the thermostat housing and the thermostat base that are connected with each other, the temperature-sensitive body of thermostat is arranged in thermostat base, engine body coolant constitutes circulation through independent loops branch road, independent loops branch road and thermostat base disposed adjacent, the tube wall of independent loops branch road is provided with hygral equilibrium hole, the tube chamber of described hygral equilibrium hole connection independent loops branch road and thermostat base chamber.
Compared with prior art, there is techniques below effect in the present invention:
The setting in hygral equilibrium hole, allow independent loops branched portion coolant mix with thermostat base intracavity coolant so that thermostat can sense the temperature of coolant in time, and normally-open, it is to avoid phenomenon of boiling occurs.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-4, the present invention is done further details of narration.
A kind of thermostat base, it is provided with thermostat 30 between the thermostat housing 10 and the thermostat base 20 that are connected with each other, the temperature-sensitive body of thermostat 30 is arranged in thermostat base 20, engine body coolant constitutes circulation through independent loops branch road 40, independent loops branch road 40 and thermostat base 20 disposed adjacent, the tube wall of independent loops branch road 40 is provided with hygral equilibrium hole 41, and described hygral equilibrium hole 41 connects tube chamber and thermostat base 20 chamber of independent loops branch road 40.Independent loops branch road 40 can have multiple choices, and described independent loops branch road 40 circulates branch road for machine oil coolant, or circulates branch road for EGR, or circulates branch road for warm braw.
Engine body itself is arranged the compactest, method as described below is arranged, space can not only be made the compactest, simultaneously, only the tube chamber of independent loops branch road 40 need to can be made to be connected with thermostat base 20 chamber in independent loops branch road 40 upper shed: described independent loops branch road 40 intersects layout with thermostat base 20 chamber, and hygral equilibrium hole 41 is arranged on independent loops branch road 40 and is positioned on the portions of thermostat base 20 intracavity.The vertical thermostat 30 shaft core line direction of independent loops branch road 40 is arranged, and the section tubular wall of independent loops branch road 40 is connected with the tube wall of thermostat base 20, is exactly briefly that independent loops branch road 40 constitutes a cross with thermostat base 20.The cross section of independent loops branch road 40 is less than the area of section of the inner chamber of thermostat base 20, and independent loops branch road 40 and thermostat base 20 are integral type shaped component, and independent loops branch road 40 is by being attached at thermostat base 20 inwall.
The maximum bright spot being set as the present invention in hygral equilibrium hole 41, its position and pore size are worthy of careful study the most very much.Hygral equilibrium hole 41 is arranged on independent loops branch road 40 and is positioned at the pipeline section middle of thermostat base 20.Hygral equilibrium hole 41 is arranged on the side on the lower side of independent loops branch road 40, side on the lower side mentioned here, refer to: when independent loops branch road 40 arranges when, hygral equilibrium hole is offered on the downside tube wall of its vertical, when the direction of C indication during vertical is Fig. 3, it is the most suitable that its hygral equilibrium hole 41 is opened in position as shown in Figure 3；When the direction of C indication during vertical is Fig. 4, it is the most suitable that its hygral equilibrium hole 41 is opened in position as shown in Figure 4.When hygral equilibrium hole 41 being opened in independent loops branch road 40 side on the lower side, owing to the coolant of the coolant in the existence of gravity, beneficially independent loops branch road 40 with thermostat base 20 intracavity mixes.The pore size in hygral equilibrium hole 41 need to be through carrying out CAE calculating and by verification experimental verification, and the excessive circulation then affecting independent loops branch road 40 in aperture is too small, the poor effect of phenomenon of avoiding boiling.
When making, independent loops branch road 40 is positioned at portions and thermostat base 20 integral molding of thermostat base 20, connection for the ease of independent loops branch road 40, independent loops branch road 40 is positioned at thermostat base 20 pipe joint 42a, 42b arranged of outwards postponing, and such independent loops branch road 40 is positioned at the outside pipeline section of thermostat base 20 and can be connected by pipe joint 42a, 42b with thermostat base 20 inner pipe.
